OBJECTIVE To assess the influence of diaphragmatic activation control (diaphC) on Sniff Nasal-Inspiratory Pressure (SNIP) and Maximum Relaxation Rate of inspiratory muscles (MRR) in healthy subjects. METHOD Twenty subjects (9 male; age: 23 (SD=2.9) years; BMI: 23.8 (SD=3) kg/m²; FEV1/FVC: 0.9 (SD=0.1)] performed 5 sniff maneuvers in two different moments: with or without instruction on diaphC...

We have read with interest the article by HANSEN et al. [1] in a recent issue of the European Respiratory Journal, stating that the use of forced expiratory volume in six seconds (FEV6) reduces the sensitivity of obstructive lung disease detection. Their study population of 3,515 current smokers, with a 17.5% prevalence of obstruction, found a sensitivity of only 76.8% and a specificity of 98.2...

The aim of the study was to test the efficacy of a one month in-patient naturopathy and yoga programme for patients with asthma. Retrospective data of 159 bronchial asthma patients, undergoing the naturopathy and yoga programme, was analyzed for Forced Vital Capacity, Forced Expiratory Volume at the end of 1 second, Maximum Voluntary Ventilation and Peak Expiratory Flow Rate on admission, 11th ...

In normal subjects and patients with airway obstruction, flows during a forced vital capacity (FVC) manoeuvre are higher after a fast inspiration without an end-inspiratory pause (manoeuvre 1) as compared to a slow inspiration with an end-expiratory pause of approximately 5 s (manoeuvre 2). In this study, we investigated the influence of these manoeuvres on maximal expiratory volume-time and fl...

The aim of this study was to describe spirometric reference equations for healthy never-smoking European adults aged 65-85 yrs and to compare the predicted values of this sample with those from other studies including middle-aged and/or older adults. Reference equations and normal ranges for forced expiratory volume in one second (FEV1), forced vital capacity (FVC), forced expiratory volume in ...

OBJECTIVE Cardiovascular, respiratory and musculoskeletal system disorders which may affect the functional exercise capacity are common in obese patients. We aimed to investigate the functional exercise capacity and its relationship with functional pulmonary capacity in obese children. METHODS A total of 74 obese and 36 healthy children as a control group were enrolled in the study. Pulmonary...
